1 Claim.

This invention relates to bobbin supports, and aims to provide an improved means for mounting roving bobbins on the creeis of spinning frames and the like.

5 The invention relates particularly to a bobbin support of the type shown in U. S. Patent No. 1,692,441, issued November 20, 1928 to my assignee, Eclipse Textile Devices, Inc., in which the bobbin is suspended by one end from a single bearing. In the device shown in that patent, the bearing is formed to serve at the saine time as a universal joint, permitting a limited tipping of the bobbin. In accordance with my present invention, the bobbin is suspended from a bearing and a separate joint which permits unlimited tipping thereof in all directions.

In my aforesaid patent, the bobbin was gripped directly by the rotary member of the bobbin support and was used without a skewer, so that some change in the habits of the operatives was required. In accordance with the present invention this inconvenience is avoided by providing for supporting the bobbin on a skewer. At the same time, the irregular friction caused by the .35 ordinary skewer mounting is avoided, and the advantages of a suspended mounting are secured.

In order that the invention may be clearly understood, I will describe in detail specic embodiments of it, which are shown in the accompanying drawing in which:

Fig. 1 is a transverse sectional elevation of the upper part of a spinning frame of usual construction, showing the creel provided with bobbin supports embodying the invention; and

Fig. 2 is an enlarged axial section of o-ne of the bobbin supports shown in Fig. 1.

The bobbin support illustrated includes a fixed supporting member 10 secured to one of the creelboards C, and a rotary member 12 connected to the fixed member l@ by a single bearing 11. The

xed and rotary members 10 and 12 are provided with opposed bearing surfaces 13 and 14, which serve as races for bearing balls 15 interposed between them. It is desirable, but not essential, to make one of the bearing surfaces, for example, the surface 13, spherically curved as in my aforesaid patent.

The rotary member 12 is very short, and has 60 secured to its bottom a hook 16 from which is suspended an eye 17 secured in the upper end of a skewer S carrying a bobbin B. The skewer S diners from the ordinary skewer only in that the projecting upper end of such a skewer, which ordinarily enters a socket in the upper Creel-board, is replaced by the eye 17. The skewer S is suspended With its lower end clear of the creelboard C1 below it, instead of with its lower end in a cup on this creel shown as in the usual skewer mounting.

The hook and eye 16 and 17 provide an articulated joint which permits the bobbin to hang with its center of gravity directly below its point of support, regardless of a lack of symmetry in the winding of the roving or a lack of accuracy in the attachment of the xed member 10 to the Creel-board. This fact, coupled with the fact that the lower end of the skewer and bobbin are entirely free, makes the rotational resistance very slight and perfectly even as the roving is drawn oiT the bobbin.

Operatives may replace the bobbins without any change in their habits, since the up and down motion required to hook or unhook the eye of the skewer is the same as that required to place a skewer in the ordinary socket and cup mounting.

What I claim is:

A bobbin support for the creels of spinning frames, comprising a xed member, a rotary member, a bearing between the fixed and rotary members formed to permit the rotary member to tip with respect to the iixed member, and a hook and eye connecting a bobbin to the rotary member and permitting the bobbin to tip with respect to the rotary member.
